By reviewing the ancient and modern literature, the name, origin, scientific name evolution, place of origin, quality, harvesting, processing, efficacy and toxicity of Asteris Radix et Rhizoma(ARR) were systematically sorted out, so as to provide reference for the development and utilization of the relevant famous classical formulas. According to textual research, ARR was first contained in Shennong Bencaojing, all generations are Ziwan for its proper name, and there are still aliases such as Ziyuan, Ziqian and Xiaobianer. Its mainstream origin in successive generations was Aster tataricus, and there are also Ligularia fischeri and others in local area of use. The medicinal parts of ARR are root and rhizome, but in modern times, the rhizome is mostly used for propagation and cultivation, so some of ARR medicinal materials only have the root without the rhizome. The earliest recorded ancient origin of ARR was now Fangxian(Hubei), Zhengding and Handan(Heibei), then the range of production areas gradually expanded, the mainstream production areas from the Song dynasty to the Ming and Qing dynasties included Hebei, Jiangsu, Anhui, Henan and other places, since modern times, two major producing areas have been formed in Anguo, Hebei province and Bozhou, Anhui province. From the quality evaluation, it is clear that from ancient times, flexible roots and purple color are the best. The ancient harvesting was mainly in lunar February or March, and then dried in the shade, and the modern harvesting is mostly in spring and autumn, and the roots are braided into pigtails and then dried in the sun or dried in the sun after 1-2 d. The ancient and modern processing method of ARR are basically the same, mainly honey processing, there are still methods of frying, steaming, vinegar sizzling, etc. Based on the results, it is recommended that the dried roots and rhizomes of A. tataricus should be used in clinical and the development of related famous classical formulas, and those whose original formulas specify the processing requirements can be processed according to the relevant requirements, while whose processing requirements are not specified should be used in the form of raw products.

The use of tyrosine kinase inhibitors (TKI) has been an important advance in the systemic treatment of hepatocellular carcinoma, but their sustained anti-angiogenic therapy leads to increased tumor hypoxia, accelerates the development of a hypoxic microenvironment and promotes the expressions of hypoxia-inducible factors (HIF), thereby inducing drug resistance of tumor patients to TKI. This paper summarizes the mechanism of action of HIF mediating TKI resistance in hepatocellular carcinoma in aspects of metabolic reprogramming, abnormal expressions of cancer and cancer-associated genes, and ferroptosis, and sorts resistance response strategies to provide reference for clinical solutions to TKI resistance issues. As results show, HIF/ glycolysis axis inhibitors (isoflavonoid genistein, simvastatin, etc.) can improve TKI resistance based on metabolic reprogramming mechanism; oncogene-targeted inhibitors combined with TKI (the combination of capsaicin and sorafenib) can improve TKI resistance based on abnormal expression of cancer and cancer-related genes; fatty acid synthase inhibitor (orlistat) can improve TKI resistance based on ferroptosis mechanism.

By consulting ancient and modern literature, the herbal textual research of Farfarae Flos has been conducted to verify the name, origin, producing area, quality evaluation, harvesting and processing methods, so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research, the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing(《神农本草经》), and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara, in addition, the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar, and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei, Gansu, Shaanxi are the authentic producing areas with the good quality products. Since modern times, its quality is summarized as big, fat, purple-red color, no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty, and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results, it is suggested that the dried flower buds of T. farfara, a Compositae plant, should be selected for the development of famous classical formulas containing Farfarae Flos, and the corresponding processed products should be selected according to the specific processing requirements of the formulas, and raw products are recommended for medicinal use without indicating processing requirements.

Objective:To explore the effectiveness of modified objective structured clinical examination (OSCE) for evaluating the core competencies of new nurses on standardized training in neurosurgery.Methods:Thirty-seven new nurses on standardized training in neurosurgery were evaluated using a modified OSCE protocol that was focused on core competencies required for clinical nursing practice on the basis of a clinical case library, which consisted of diagnostic assessment upon entrance, process teaching evaluation during training, and outcome assessment upon exit, at five OSCE stations (nursing assessment, skill practice, clinical thinking, health education, and humanistic care). SPSS 26.0 was used to perform the t-test and rank sum test. Results:The nurses highly recognized the effectiveness of modified OSCE and were largely satisfied with teaching. There were significant differences at entrance and exit in terms of the mean OSCE score ( t=24.21, P<0.001), independent learning ability ( t=10.29, P<0.001), and the scores of core competencies—good personal traits ( Z=5.24, P<0.001), clinical nursing ability ( Z=5.07, P<0.001), support and interpersonal communication ability ( Z=5.12, P<0.001), critical clinical thinking ability ( Z=5.17, P<0.001), professional construction and self-development ( Z=5.05, P<0.001), and the total score ( Z=5.27, P<0.001). Conclusions:The modified OSCE can comprehensively evaluate the core competencies of new nurses in neurosurgery standardized training, with good feasibility and effectiveness, which provides a reference for teaching management of standardized training programs.

Objective:To analyze the association between sleep status and ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.Methods:It was a cross sentional study. Hypertensive patients who underwent 24-hour ambulatory blood pressure monitoring from May 2021 to April 2023 in Shanghai Xinzhuang Town were enrolled. The demographic information and sleep status of patients were obtained from the questionnaire. A TM-2430 blood pressure monitor was used to measure 24-hour ambulatory blood pressure, and the relevant indicators, including blood pressure level and blood pressure coefficient of variation were documented. The association between sleep status and blood pressure indicators was analyzed with multivariate linear regression model.Results:A total 1 135 patients aged (65.07±12.61) years were enrolled, and 473 (41.67%) of whom were males. The sleep time was<7 hours in 76 cases, 7- 8 hours in 219 cases and >8 hours in 840 cases; the bedtime was earlier than 22∶00 in 415 cases, between 22∶00 and 23∶00 in 474 cases and later than 23∶00 in 246 cases; the wake-up time was before 6∶00 in 230 cases, between 6∶00 and 7∶00 in 521 cases and after 7∶00 in 384 cases. Multivariate linear regression analysis showed that after controlling for gender and age, the sleep time was negatively associated with diurnal, noctumal and 24-hour diastolic blood pressure levels (all P<0.05), and positively associated with diurnal and noctumal systolic blood pressure coefficient of variation, noctumal diastolic blood pressure coefficient of variation, and 24-hour systolic blood pressure coefficient of variation (all P<0.05).The bedtime was positively associated with diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), diastolic blood pressure (all P<0.05); and negatively associated with diurnal systolic blood pressure coefficient of variation, diurnal diastolic blood pressure coefficient of variation, noctumal systolic blood pressure coefficient of variation, 24-hour systolic blood pressure coefficient of variation, and 24-hour diastolic blood pressure coefficient of variation (all P<0.05). The wake-up time was positively associated with diurnal systolic blood pressure, diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), and positively associated with diurmal systolic blood pressure and diastolic blood pressure (both P<0.05). Conclusion:Sleep status is closely associated with ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.
